An area plot is the continuous analog of a stacked bar
geom_bar), and can be used to
show how composition of the whole varies over the range
of x. Choosing the order in which different components
is stacked is very important, as it becomes increasing
hard to see the individual pattern as you move up the
geom_area(mapping = NULL, data = NULL, stat = "identity", position = "stack", na.rm = FALSE, ...)
- The aesthetic mapping, usually constructed
aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
- A layer specific dataset - only needed if you want to override the plot defaults.
- The statistical transformation to use on the data for this layer.
- The position adjustment to use for overlappling points on this layer
FALSE(the default), removes missing values with a warning. If
TRUEsilently removes missing values.
- other arguments passed on to
layer. This can include aesthetics whose values you want to set, not map. See
layerfor more details.
An area plot is a special case of
geom_ribbon, where the minimum of the range
is fixed to 0, and the position adjustment defaults to
